A cloud provider is designing its infrastructure to support both virtual machines and containerized applications. The provider wants to ensure that network policies can be applied consistently across both environments, regardless of the underlying physical network. Which approach should the provider take?

Configure the same VLANs for both environments

Use SDN to create a programmable overlay that abstracts the physical network and applies policies consistently

Deploy a firewall in each hypervisor

Use separate physical networks for VMs and containers

What is the purpose of the OpenFlow protocol in an SDN environment?

To replace BGP for inter-domain routing

To enable communication between the SDN controller and the data plane switches

To encrypt all data traffic in the network

To provide a northbound API for network applications

How does SDN relate to Network Functions Virtualization (NFV) in a cloud environment?

SDN is a type of NFV that virtualizes only the control plane

SDN provides the programmable network fabric that can dynamically connect and steer traffic between virtualized network functions (VNFs)

SDN and NFV are interchangeable terms for the same technology

SDN is a prerequisite for NFV; NFV cannot function without SDN

What is a common challenge when implementing SDN in a cloud environment?

SDN requires proprietary hardware from a single vendor

SDN cannot be integrated with existing network infrastructure

The controller becomes a potential single point of failure

SDN eliminates the need for network security

Part of the Cloud Infrastructure (NFV and SDN) domain, which makes up ~19% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–11 in this domain), expect 1–2 from this objective — we provide 29 practice questions to prepare you well beyond it.

A network engineer is troubleshooting an SDN environment where the controller is not receiving any packets from a switch when a new flow arrives. The switch is configured to send unmatched packets to the controller. Which OpenFlow message is the switch expected to send?
